Apparatus and methods are provided for RRM measurement in the NR network. In one novel aspect, the RRM measurement is configured with one measurement gap for SS block and CSI-RS. In one embodiment, an extended MGL (eMGL) is configured such that the SS block and CSI-RS is measurement within one measurement gap. In another embodiment, the shorter MGL (sMGL) that is shorter than the standard MGL is configured. In another novel aspect, the CSI-RS is allocated adjacent to the SS blocks such that one measurement gap is configured for both the SS block and CSI-RS measurement. In another novel aspect, the CSI-RS measurement is conditionally configured. In yet another novel aspect, the UE decodes the time index of the SS block conditionally.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein a single common measurement duration and a single common measurement timing offset are configured for different CSI-RS resources.
3. The method of claim 2, wherein each CSI-RS is configured with one or more parameters comprising: a cell identification (ID), a scrambling ID, a periodicity and timing offset of the CSI-RS, a measurement bandwidth of the CSI-RS, a frequency location, a numerology of the CSI-RS, and a quasi-co-location (QCL) of the CSI-RS.
4. The method of claim 1, wherein each CSI-RS configuration reuses a beam management configuration of each corresponding CSI-RS if its corresponding cell ID indicates a serving cell.
5. The method of claim 1, wherein the RRM configuration and the measurement gap configuration are configured by dedicated signaling.
6. The method of claim 1, wherein the CSI-RS is allocated in a physical downlink shared channel (PDSCH) symbol after the SS block.
7. The method of claim 1, wherein the SS block is an SS burst block across multiple analog beams, and wherein CSI-RS is allocated in a physical downlink shared channel (PDSCH) symbol after the SS block.
8. The method of claim 7, wherein the same analog beamforming applies to both the SS burst block and the CSI-RS burst block.
10. The UE of claim 9, wherein a single common measurement duration and a single common measurement timing offset are configured for different CSI-RS resources.
11. The UE of claim 10, wherein each CSI-RS is configured with one or more parameters comprising: a cell identification (ID), a scrambling ID, a periodicity and timing offset of the CSI-RS, a measurement bandwidth of the CSI-RS, a frequency location, a numerology of the CSI-RS, and a quasi-co-location (QCL) of the CSI-RS.
12. The UE of claim 9, wherein each CSI-RS configuration reuses a beam management configuration of each corresponding CSI-RS if its corresponding cell ID indicates a serving cell.
13. The UE of claim 9, wherein the RRM configuration and the measurement gap configuration are configured by dedicated signaling.
14. The UE of claim 9, wherein the CSI-RS is allocated in a physical downlink shared channel (PDSCH) symbol after the SS block.
15. The UE of claim 9, wherein the SS block is an SS burst block across multiple analog beams, and wherein CSI-RS is allocated in a physical downlink shared channel (PDSCH) symbol after the SS block.
16. The UE of claim 15, wherein the same analog beamforming applies to both the SS burst block and the CSI-RS burst block.
